May be this post (Secure Metro JAX-WS UsernameToken Web Service with Signature, Encryption and TLS (SSL)) provides more insight. As they mentioned "Remember, unless password text or digested password is sent on a secured channel or the token is encrypted, neither password digest nor cleartext password offers no real additional security. "

We can create a function as this

CREATE Function [dbo].[fn_CSVToTable] 
(
    @CSVList Varchar(max)
)
RETURNS @Table TABLE (ColumnData VARCHAR(100))
AS
BEGIN
    IF RIGHT(@CSVList, 1) <> ','
    SELECT @CSVList = @CSVList + ','

    DECLARE @Pos    BIGINT,
            @OldPos BIGINT
    SELECT  @Pos    = 1,
            @OldPos = 1

    WHILE   @Pos < LEN(@CSVList)
        BEGIN
            SELECT  @Pos = CHARINDEX(',', @CSVList, @OldPos)
            INSERT INTO @Table
            SELECT  LTRIM(RTRIM(SUBSTRING(@CSVList, @OldPos, @Pos - @OldPos))) Col001

            SELECT  @OldPos = @Pos + 1
        END

    RETURN
END

We can then seperate the CSV values into our respective columns using a SELECT statement

This can happen if a comma is missing. I ran into it when I had a list of two-tuples, each of which consisted of a string in the first position, and a list in the second. I erroneously omitted the comma after the first component of a tuple in one case, and the interpreter thought I was trying to index the first component.

@icktoofay was close with the CData

<myxml>
    <record>
        <![CDATA[
        Line 1 <br />
        Line 2 <br />
        Line 3 <br />
        ]]>
    </record>
</myxml>

Since 2.5 you can use equivalent of C’s ”?:” ternary conditional operator and the syntax is:

[on_true] if [expression] else [on_false]

So your example is fine, but you've to simply add else, like:

print a if b else ''

Because the TOP 1 from the ordered sub-query does not have profile_id = 'u162231993' Remove where u.id = 'u162231993' and see results then.

Run the sub-query separately to understand what's going on.

xxd -p file

Or if you want it all on a single line:

xxd -p file | tr -d '\n'

You can use,

func addAll(from: [String: Any], into: [String: Any]){
    from.forEach {into[$0] = $1}
}

You Should use @JsonBackReference with @ManyToOne entity and @JsonManagedReference with @onetomany containing entity classes.

@OneToMany(
            mappedBy = "queue_group",fetch = FetchType.LAZY,
            cascade = CascadeType.ALL
        )
    @JsonManagedReference
    private Set<Queue> queues;



@ManyToOne(cascade=CascadeType.ALL)
        @JoinColumn(name = "qid")
       // @JsonIgnore
        @JsonBackReference
        private Queue_group queue_group;

One more suggestion is that you can use GIMP.

Just load the PDF file in GIMP->save as .xcf and then you can do whatever you want to the image.

I added in android.support.design.widget.NawigationView this parameter:

android:layout_gravity="start"

And problem was solved.

The main issue with your example that you can't implicitly convert Task<T> return types to the base T type. You need to use the Task.Result property. Note that Task.Result will block async code, and should be used carefully.

Try this instead:

public List<int> TestGetMethod()  
{  
    return GetIdList().Result;  
}

From Java 9 there is some optimizations in replace method.

In Java 8 it uses a regex.

public String replace(CharSequence target, CharSequence replacement) {
    return Pattern.compile(target.toString(), Pattern.LITERAL).matcher(
            this).replaceAll(Matcher.quoteReplacement(replacement.toString()));
}

From Java 9 and on.

And Stringlatin implementation.

Which perform way better.

As per your request I have put this in an answer for you.

As Hieu Nguyen suggested in his answer, you can use the ajaxurl javascript variable to reference the admin-ajax.php file. However this variable is not declared on the frontend. It is simple to declare this on the front end, by putting the following in the header.php of your theme.

<script type="text/javascript">
    var ajaxurl = "<?php echo admin_url('admin-ajax.php'); ?>";
</script>

As is described in the Wordpress AJAX documentation, you have two different hooks - wp_ajax_(action), and wp_ajax_nopriv_(action). The difference between these is:

• wp_ajax_(action): This is fired if the ajax call is made from inside the admin panel.
• wp_ajax_nopriv_(action): This is fired if the ajax call is made from the front end of the website.

Everything else is described in the documentation linked above. Happy coding!

P.S. Here is an example that should work. (I have not tested)

Front end:

<script type="text/javascript">
    jQuery.ajax({
        url: ajaxurl,
        data: {
            action: 'my_action_name'
        },
        type: 'GET'
    });
</script>

Back end:

<?php
    function my_ajax_callback_function() {
        // Implement ajax function here
    }
    add_action( 'wp_ajax_my_action_name', 'my_ajax_callback_function' );    // If called from admin panel
    add_action( 'wp_ajax_nopriv_my_action_name', 'my_ajax_callback_function' );    // If called from front end
?>

UPDATE Even though this is an old answer, it seems to keep getting thumbs up from people - which is great! I think this may be of use to some people.

WordPress has a function wp_localize_script. This function takes an array of data as the third parameter, intended to be translations, like the following:

var translation = {
    success: "Success!",
    failure: "Failure!",
    error: "Error!",
    ...
};

So this simply loads an object into the HTML head tag. This can be utilized in the following way:

Backend:

wp_localize_script( 'FrontEndAjax', 'ajax', array(
    'url' => admin_url( 'admin-ajax.php' )
) );

The advantage of this method is that it may be used in both themes AND plugins, as you are not hard-coding the ajax URL variable into the theme.

On the front end, the URL is now accessible via ajax.url, rather than simply ajaxurl in the previous examples.

This could be a little tricky thing but the secure way is to set a javascript cookie, then picking it up by php cookie variable.Then Assign this php variable to an php session that will hold the data more securely than cookie.Then delete the cookie using javascript and redirect the page to itself. Given that you have added an php command to catch the variable, you will get it.

When using Rails 5 (currently still in beta), there's a new method, parsed_body on the test response, which will return the response parsed as what the last request was encoded at.

The commit on GitHub: https://github.com/rails/rails/commit/eee3534b

df.columns = ['_'.join(tup).rstrip('_') for tup in df.columns.values]

Check the error_reporting flag, must be E_ALL, but in some release of Plesk there are quotes ("E_ALL") instead of (E_ALL)

I solved this issue deleting the quotes (") in php.ini

from this:

error_reporting = "E_ALL"

to this:

error_reporting = E_ALL

you can use LINQ

string abc = "abc";
char getresult = abc.Where((item, index) => index == 2).Single();

Just add

spring.flyway.enabled=false

in application.properties file if you do not want flyway to check the checksum every time you run the application.

Try setting the parameters' "default value" to use the same query as the "available values". In effect it provides every single "available value" as a "default value" and the "Select All" option is automatically checked.

FileZilla does not have any command line arguments (nor any other way) that allow an automatic transfer.

Some references:

• FileZilla Client command-line arguments
• https://trac.filezilla-project.org/ticket/2317
• How do I send a file with FileZilla from the command line?

Though you can use any other client that allows automation.

You have not specified, what protocol you are using. FTP or SFTP? You will definitely be able to use WinSCP, as it supports all protocols that FileZilla does (and more).

Combine WinSCP scripting capabilities with Windows Scheduler:

• Automate file transfers to FTP server or SFTP server;
• Schedule file transfers to FTP/SFTP server

A typical WinSCP script for upload (with SFTP) looks like:

open sftp://user:[email protected]/ -hostkey="ssh-rsa 2048 xxxxxxxxxxx...="
put c:\mypdfs\*.pdf /home/user/
close

With FTP, just replace the sftp:// with the ftp:// and remove the -hostkey="..." switch.

Similarly for download: How to schedule an automatic FTP download on Windows?

WinSCP can even generate a script from an imported FileZilla session.

For details, see the guide to FileZilla automation.

(I'm the author of WinSCP)

Another option, if you are using SFTP, is the psftp.exe client from PuTTY suite.

From ios 10.0 we need set { self.orientations = newValue } for setting up the orientation, Make sure landscape property is enabled in your project.

private var orientations = UIInterfaceOrientationMask.landscapeLeft
override var supportedInterfaceOrientations : UIInterfaceOrientationMask {
    get { return self.orientations }
    set { self.orientations = newValue }
}

I typically abbreviate so that I can use several places in my code. Near the top, do something like this:

 string nl = System.Environment.NewLine;

Then I can just use "nl" instead of the full qualification everywhere when constructing strings.

I liked the approach followed by chocolatey, as posted in anonymous coward's answer, since it is a pure batch approach. However, it leaves a temporary file and some temporary variables lying around. I made a cleaner version for myself.

Make a file refreshEnv.bat somewhere on your PATH. Refresh your console environment by executing refreshEnv.

It happened to me when the auto formatter in a visual studio project sorted my includes after which the pre compiled header was not the first include anymore.

In other words. If you have any of these:

#include "pch.h"

or

#include <stdio.h>

or

#include <iostream>
#include "stdafx.h"

Put it at the start of your file.

If your clang formatter is sorting the files automatically, try putting an enter after the pre compiled header. If it is on IBS_Preserve it will sort each #include block separately.

#include "pch.h"  // must be first

#include "bar.h"  // next block
#include "baz.h"
#include "foo.h"

You are correct that a stack is 'just' a data structure. Here, however, it refers to a hardware implemented stack used for a special purpose --"The Stack".

Many people have commented about hardware implemented stack versus the (software)stack data structure. I would like to add that there are three major stack structure types -

1. A call stack -- Which is the one you are asking about! It stores function parameters and return address etc. Do read Chapter 4 ( All about 4th page i.e. page 53)functions in that book. There is a good explanation.
2. A generic stack Which you might use in your program to do something special...
3. A generic hardware stack
   I am not sure about this, but I remember reading somewhere that there is a general purpose hardware implemented stack available in some architectures. If anyone knows whether this is correct, please do comment.

The first thing to know is the architecture you are programming for, which the book explains (I just looked it up --link). To really understand things, I suggest that you learn about the memory, addressing, registers and architecture of x86 (I assume thats what you are learning --from the book).

seems like in Angular 1.3.12 you do not need the inner ng-repeat anymore, the outer loop returns the values of the collection is a single map entry

This looks like valid Python code, so if the file is on your project's classpath (and not in some other directory or in arbitrary places) one way would be just to rename the file to "abc.py" and import it as a module, using import abc. You can even update the values using the reload function later. Then access the values as abc.path1 etc.

Of course, this can be dangerous in case the file contains other code that will be executed. I would not use it in any real, professional project, but for a small script or in interactive mode this seems to be the simplest solution.

Just put the abc.py into the same directory as your script, or the directory where you open the interactive shell, and do import abc or from abc import *.

Singletons aren't evil, if you use it properly & minimally. There are lot of other good design patterns which replaces the needs of singleton at some point (& also gives best results). But some programmers are unaware of those good patterns & uses the singleton for all the cases which makes the singleton evil for them.

I don't know why the other solutions go through the whole list of stylesheets for the document. Doing so creates a new entry in each stylesheet, which is inefficient. Instead, we can simply append a new stylesheet and simply add our desired CSS rules there.

style=document.createElement('style');
document.head.appendChild(style);
stylesheet=style.sheet;
function css(selector,property,value)
{
    try{ stylesheet.insertRule(selector+' {'+property+':'+value+'}',stylesheet.cssRules.length); }
    catch(err){}
}

Note that we can override even inline styles set directly on elements by adding " !important" to the value of the property, unless there already exist more specific "!important" style declarations for that property.

Updated answer for Django migrations without south plugin:

Like T.T suggested in his answer, my previous answer was for south migration plugin, when Django hasn't any schema migration features. Now (works in Django 1.9+):

T.T wrote:

You can try this!

python manage.py makemigrations

python manage.py migrate --run-syncdb

Outdated for south migrations plugin

As I can see you done it all in wrong order, to fix it up your should complete this checklist (I assume you can't delete sqlite3 database file to start over):

1. Grab any SQLite GUI tool (i.e. http://sqliteadmin.orbmu2k.de/)
2. Change your model definition to match database definition (best approach is to comment new fields)
3. Delete migrations folder in your model
4. Delete rows in south_migrationhistory table where app_name match your application name (probably homework)
5. Invoke: ./manage.py schemamigration <app_name> --initial
6. Create tables by ./manage.py migrate <app_name> --fake (--fake will skip SQL execute because table already exists in your database)
7. Make changes to your app's model
8. Invoke ./manage.py schemamigration <app_name> --auto
9. Then apply changes to database: ./manage.py migrate <app_name>

Steps 7,8,9 repeat whenever your model needs any changes.

These functions have been very helpful to me - especially in setting up subscription reports; however, I noticed when using the Last Day of Current Month function posted above, it works as long as the proceeding month has the same number of days as the current month. I have worked through and tested these modifications and hope they help other developers in the future:

Date Formulas: Find the First Day of Previous Month:

DateAdd("m", -1, DateSerial(Year(Today()), Month(Today()), 1))

Find Last Day of Previous Month:

DateSerial(Year(Today()), Month(Today()), 0)

Find First Day of Current Month:

DateSerial(Year(Today()),Month(Today()),1)

Find Last Day of Current Month:

DateSerial(Year(Today()),Month(DateAdd("m", 1, Today())),0)

I got a same problem. Below is how I solved the problem. I am working on an oracle database 12c pluggable database(pdb) on a windows 10.

-- using sqlplus to login as sysdba from a terminal; Below is an example:

sqlplus sys/@orclpdb as sysdba

-- First check your database status;

SQL> select name, open_mode from v$pdbs;

-- It shows the database is mounted in my case. If yours is not mounted, you should mount the database first.

-- Next open the database for read/write

SQL> ALTER PLUGGABLE DATABASE OPEN; (or ALTER PLUGGABLE DATABASE YOURDATABASENAME OPEN;)

-- Check the status again.

SQL> select name, open_mode from v$pdbs;

-- Now your dababase should be open for read/write and you should be able to create schemas, etc.

another workaround:

var myarray = [];
$("#test").click(function() {
    myarray[index]=$("#drop").val();
    alert(myarray);
});

i wanted to add all checked checkbox to array. so example, if .each is used:

var vpp = [];
var incr=0;
$('.prsn').each(function(idx) {
   if (this.checked) {
       var p=$('.pp').eq(idx).val();
       vpp[incr]=(p);
       incr++;
   }
});
//do what ever with vpp array;

In my case it turns out my
new server was running MySQL 5.5,
old server was running MySQL 5.6.
So I got this error when trying to import the .sql file I'd exported from my old server.

MySQL 5.5 does not support utf8mb4_unicode_520_ci, but
MySQL 5.6 does.

Updating to MySQL 5.6 on the new server solved collation the error !

If you want to retain MySQL 5.5, you can:
- make a copy of your exported .sql file
- replace instances of utf8mb4unicode520_ci and utf8mb4_unicode_520_ci
...with utf8mb4_unicode_ci
- import your updated .sql file.

Check out: http://commons.apache.org/io/

It has copy, and as stated the JDK already has move.

Don't implement your own copy method. There are so many floating out there...

I got this when I forgot the -m in my git commit when resolving a git merge conflict.

git commit "commit message"

should be

git commit -m "commit message"

This code may be helpful

L ={x, y, z}
T= ((0,"c"),(1,"d"),(2,"e"),(3,"f"),)
List2=[]
for t in T :
if t[0] in L :
    List2.append(t[1])
    break;

To remove four characters from the end of the string use ${var%????}.

To remove everything after the final . use ${var%.*}.

A variation on SquareRootOf2's answer, but this should be placed before the first use of the $output variable:

$keys = array('key1', 'key2', 'etc');
$output = array_fill_keys($keys, '');

It seems to be a bug, it work for all input type that aren't textbox (checkboxes, radio,...)

There is a quick workaround that will work.

<div data-tip="This is the text of the tooltip2">
    <input type="text" name="test" value="44"/>
</div>

JsFiddle

If you have jQuery UI (needed for the datepicker), this would do the trick:

$.datepicker.formatDate('yy/mm/dd', new Date());

For a string of length 1 you can simply perform isdigit() or isalpha()

If your string length is greater than 1, you can make a function something like..

def isinteger(a):
    try:
        int(a)
        return True
    except ValueError:
        return False

About your command line:

root@debian:/# sudo iptables -A INPUT -p tcp --dport 3306 --jump ACCEPT
root@debian:/# iptables-save

• You are already authenticated as root so sudo is redundant there.

• You are missing the -j or --jump just before the ACCEPT parameter (just tought that was a typo and you are inserting it correctly).

About yout question:

If you are inserting the iptables rule correctly as you pointed it in the question, maybe the issue is related to the hypervisor (virtual machine provider) you are using.

If you provide the hypervisor name (VirtualBox, VMWare?) I can further guide you on this but here are some suggestions you can try first:

check your vmachine network settings and:

• if it is set to NAT, then you won't be able to connect from your base machine to the vmachine.

• if it is set to Hosted, you have to configure first its network settings, it is usually to provide them an IP in the range 192.168.56.0/24, since is the default the hypervisors use for this.

• if it is set to Bridge, same as Hosted but you can configure it whenever IP range makes sense for you configuration.

Hope this helps.

Take a look at the Event Log API. Case a) (bluescreen, user cut the power cord or system hang) causes a note ('system did not shutdown correctly' or something like that) to be left in the 'System' event log the next time the system is rebooted properly. You should be able to access it programmatically using the above API (honestly, I've never used it but it should work).

The number of digits of an integer n in any base is trivially obtained by dividing until you're done:

unsigned int number_of_digits = 0;

do {
     ++number_of_digits; 
     n /= base;
} while (n);

If the class uses as a parameterized type, it can declare an array of type T[], but it cannot directly instantiate such an array. Instead, a common approach is to instantiate an array of type Object[], and then make a narrowing cast to type T[], as shown in the following:

  public class Portfolio<T> {
  T[] data;
 public Portfolio(int capacity) {
   data = new T[capacity];                 // illegal; compiler error
   data = (T[]) new Object[capacity];      // legal, but compiler warning
 }
 public T get(int index) { return data[index]; }
 public void set(int index, T element) { data[index] = element; }
}

To check your stash content :-

git stash list

apply a particular stash no from stash list:-

git stash apply stash@{2}

or for applying just the first stash:-

git stash pop

Note: git stash pop will remove the stash from your stash list whereas git stash apply wont. So use them accordingly.

Use

 mediaplayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
 mediaplayer.prepareAsync();
 mediaplayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
      @Override
      public void onPrepared(MediaPlayer mp) {
          mediaplayer.start();
      }
 });

The arguments object is where the functions arguments are stored.

The arguments object acts and looks like an array, it basically is, it just doesn't have the methods that arrays do, for example:

Array.forEach(callback[, thisArg]);

Array.map(callback[, thisArg])

Array.filter(callback[, thisArg]);

Array.slice(begin[, end])

Array.indexOf(searchElement[, fromIndex])

I think the best way to convert a arguments object to a real Array is like so:

argumentsArray = [].slice.apply(arguments);

That will make it an array;

reusable:

function ArgumentsToArray(args) {
    return [].slice.apply(args);
}

(function() {
   args = ArgumentsToArray(arguments);

   args.forEach(function(value) {
      console.log('value ===', value);
   });

})('name', 1, {}, 'two', 3)

result:

> value === name
> value === 1
> value === Object {}
> value === two
> value === 3

As far as I'm aware in order to format a date value you have to handle it in parameterMap,

$('#listDiv').kendoGrid({
            dataSource: {
                type: 'json',
                serverPaging: true,
                pageSize: 10,
                transport: {
                    read: {
                        url: '@Url.Action("_ListMy", "Placement")',
                        data: refreshGridParams,
                        type: 'POST'
                    },
                    parameterMap: function (options, operation) {
                        if (operation != "read") {
                            var d = new Date(options.StartDate);
                            options.StartDate = kendo.toString(new Date(d), "dd/MM/yyyy");
                            return options;
                        }
                        else { return options; }

                    }
                },
                schema: {
                    model: {
                        id: 'Id',
                        fields: {
                            Id: { type: 'number' },
                            StartDate: { type: 'date', format: 'dd/MM/yyyy' },
                            Area: { type: 'string' },
                            Length: { type: 'string' },
                            Display: { type: 'string' },
                            Status: { type: 'string' },
                            Edit: { type: 'string' }
                        }
                    },
                    data: "Data",
                    total: "Count"
                }
            },
            scrollable: false,
            columns:
                [
                    {
                        field: 'StartDate',
                        title: 'Start Date',
                        format: '{0:dd/MM/yyyy}',
                        width: 100
                    },

If you follow the above example and just renames objects like 'StartDate' then it should work (ignore 'data: refreshGridParams,')

There is no way to identify the charset of a string that is completely accurate. There are ways to try to guess the charset. One of these ways, and probably/currently the best in PHP, is mb_detect_encoding(). This will scan your string and look for occurrences of stuff unique to certain charsets. Depending on your string, there may not be such distinguishable occurrences.

Take the ISO-8859-1 charset vs ISO-8859-15 ( http://en.wikipedia.org/wiki/ISO/IEC_8859-15#Changes_from_ISO-8859-1 )

There's only a handful of different characters, and to make it worse, they're represented by the same bytes. There is no way to detect, being given a string without knowing it's encoding, whether byte 0xA4 is supposed to signify ¤ or € in your string, so there is no way to know it's exact charset.

(Note: you could add a human factor, or an even more advanced scanning technique (e.g. what Oroboros102 suggests), to try to figure out based upon the surrounding context, if the character should be ¤ or €, though this seems like a bridge too far)

There are more distinguishable differences between e.g. UTF-8 and ISO-8859-1, so it's still worth trying to figure it out when you're unsure, though you can and should never rely on it being correct.

Interesting read: http://kore-nordmann.de/blog/php_charset_encoding_FAQ.html#how-do-i-determine-the-charset-encoding-of-a-string

There are other ways of ensuring the correct charset though. Concerning forms, try to enforce UTF-8 as much as possible (check out snowman to make sure yout submission will be UTF-8 in every browser: http://intertwingly.net/blog/2010/07/29/Rails-and-Snowmen ) That being done, at least you're can be sure that every text submitted through your forms is utf_8. Concerning uploaded files, try running the unix 'file -i' command on it through e.g. exec() (if possible on your server) to aid the detection (using the document's BOM.) Concerning scraping data, you could read the HTTP headers, that usually specify the charset. When parsing XML files, see if the XML meta-data contain a charset definition.

Rather than trying to automagically guess the charset, you should first try to ensure a certain charset yourself where possible, or trying to grab a definition from the source you're getting it from (if applicable) before resorting to detection.

Add builtin COPY in project.csproj file:

  <Project>
    ...
    <Target Name="AfterBuild">
      <Copy SourceFiles="$(ProjectDir)..\..\Lib\*.dll" DestinationFolder="$(OutDir)Debug\bin" SkipUnchangedFiles="false" />
      <Copy SourceFiles="$(ProjectDir)..\..\Lib\*.dll" DestinationFolder="$(OutDir)Release\bin" SkipUnchangedFiles="false" />
    </Target>

Best would be not using LinkedList at all, usually it is slower in all disciplines, and less handy. (When mainly inserting/deleting to the front, especially for big arrays LinkedList is faster)

Use ArrayList, and iterate with

int len = list.size();
for (int i = 0; i < len; i++) {
  Element ele = list.get(i);
}

Reset is trivial, just loop again.
If you insist on using an iterator, then you have to use a new iterator:

iter = list.listIterator();

(I saw only once in my life an advantage of LinkedList: i could loop through whith a while loop and remove the first element)

Here is the only answer that managed to work for my problem, got it figured out with the help of this webpage (nice reference).

powershell -command "& {&'some-command' someParam}"

Also, here is a neat way to do multiple commands:

powershell -command "& {&'some-command' someParam}"; "& {&'some-command' -SpecificArg someParam}"

For example, this is how I ran my 2 commands:

powershell -command "& {&'Import-Module' AppLocker}"; "& {&'Set-AppLockerPolicy' -XmlPolicy myXmlFilePath.xml}"

The solution that i believe is best and optimized is:

try:
   #your code
except "ModelName".DoesNotExist:
   #your code

Simple and easy way to get File name

File file = new File("/storage/sdcard0/DCIM/Camera/1414240995236.jpg"); 
String strFileName = file.getName();

After add this code and print strFileName you will get strFileName = 1414240995236.jpg

pst = con.createStatement(); ResultSet resultSet= pst.executeQuery(query);

     String str1 = "<table>";
     int i = 1;
    while(resultSet.next()) {
             str1+= "</tr><td>"+i+"</td>"+
             "<td>"+resultSet.getString("first_name")+"</td>"+
             "<td>"+resultSet.getString("last_name")+"</td>"+
             "<td>"+resultSet.getString("email_id")+"</td>"+
             "<td>"+resultSet.getString("dob") +"</td>"+

             "</tr>";
        i++;

    }
        str1 =str1+"<table>";

    model.addAttribute("list",str1);

    return "userlist";  //Sending to views .jsp 

You may be able to fix this error by name spacing :: the function call

comparison.cloud(colors = c("red", "green"), max.words = 100)

to

wordcloud::comparison.cloud(colors = c("red", "green"), max.words = 100)

To change the Path, you can set a new Path to an Enviroment-Variable named: VAGRANT_HOME

export VAGRANT_HOME=my/new/path/goes/here/

Thats maybe nice if you want to have those vagrant-Images on another HDD.

Delay is possible only once at the beginning with infinite. in sort delay doesn't work with infinite loop. for that you have to keep keyframes animation blanks example:

@-webkit-keyframes barshine {
  10% {background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#1e5799), color-stop(100%,#7db9e8));
    }
  60% {background: -webkit-linear-gradient(top, #7db9e8 0%,#d32a2d 100%);}
}

it will animate 10% to 60% and wait to complete 40% more. So 40% comes in delay.

You are getting a keySet iterator on the HashMap and expecting to iterate over entries.

Correct code:

    HashMap hm = new HashMap();

    hm.put(0, "zero");
    hm.put(1, "one");

    //Here we get the keyset iterator not the Entry iterator
    Iterator iter = (Iterator) hm.keySet().iterator();

    while(iter.hasNext()) {

        //iterator's next() return an Integer that is the key
        Integer key = (Integer) iter.next();
        //already have the key, now get the value using get() method
        System.out.println(key + " - " + hm.get(key));

    }

Iterating over a HashMap using EntrySet:

     HashMap hm = new HashMap();
     hm.put(0, "zero");
     hm.put(1, "one");
     //Here we get the iterator on the entrySet
     Iterator iter = (Iterator) hm.entrySet().iterator();


     //Traversing using iterator on entry set  
     while (iter.hasNext()) {  
         Entry<Integer,String> entry = (Entry<Integer,String>) iter.next();  
         System.out.println("Key = " + entry.getKey() + ", Value = " + entry.getValue());  
     }  

     System.out.println();


    //Iterating using for-each construct on Entry Set
    Set<Entry<Integer, String>> entrySet = hm.entrySet();
    for (Entry<Integer, String> entry : entrySet) {  
        System.out.println("Key = " + entry.getKey() + ", Value = " + entry.getValue());  
    }           

Look at the section -Traversing Through a HashMap in the below link. java-collection-internal-hashmap and Traversing through HashMap

empty is an operator:

The empty operator is a prefix operation that can be used to determine whether a value is null or empty.

<c:if test="${empty myObject.featuresList}">

For anybody who work in VB.NET (just in case)

Dim dv As DataView = yourDatatable.DefaultView

dv.RowFilter ="query" ' ex: "parentid = 0"

Go 1.11 will have a feature called go modules and you can simply add a dependency with a version. Follow these steps:

go mod init .
go mod edit -require github.com/wilk/[email protected]
go get -v -t ./...   
go build
go install 

Here's more info on that topic - https://github.com/golang/go/wiki/Modules

You can do a form.serializeArray(), then add name-value pairs before posting:

var form = $(this).closest('form');

form = form.serializeArray();

form = form.concat([
    {name: "customer_id", value: window.username},
    {name: "post_action", value: "Update Information"}
]);

$.post('/change-user-details', form, function(d) {
    if (d.error) {
        alert("There was a problem updating your user details")
    } 
});

Seems quite simple these days. This is the Swift version.

let tap = UITapGestureRecognizer(target: self, action: #selector(viewTapped))
    view.addGestureRecognizer(tap)

@objc func viewTapped(recognizer: UIGestureRecognizer)
{
    //Do what you need to do!
}

this is old but, use nano, vim or gvim

If you want a good format the next statement is the best:

dataframe_prediction.to_csv('filename.csv', sep=',', encoding='utf-8', index=False)

In this case you have got a csv file with ',' as separate between columns and utf-8 format. In addition, numerical index won't appear.

Your controller method should be like this:

@RequestMapping(value = " /<your mapping>/{id}", method=RequestMethod.GET)
public String listNotes(@PathVariable("id")int id,Model model) {
    Person person = personService.getCurrentlyAuthenticatedUser();
    int id = 2323;  // Currently passing static values for testing
    model.addAttribute("person", new Person());
    model.addAttribute("listPersons", this.personService.listPersons());
    model.addAttribute("listNotes",this.notesService.listNotesBySectionId(id,person));
    return "note";
}

Use the id in your code, call the controller method from your JSP as:

/{your mapping}/{your id}

UPDATE:

Change your jsp code to:

<c:forEach items="${listNotes}" var="notices" varStatus="status">
    <tr>
        <td>${notices.noticesid}</td>
        <td>${notices.notetext}</td>
        <td>${notices.notetag}</td>
        <td>${notices.notecolor}</td>
        <td>${notices.sectionid}</td>
        <td>${notices.canvasid}</td>
        <td>${notices.canvasnName}</td>
        <td>${notices.personid}</td>
        <td><a href="<c:url value='/editnote/${listNotes[status.index].noticesid}' />" >Edit</a></td>
        <td><a href="<c:url value='/removenote/${listNotes[status.index].noticesid}' />" >Delete</a></td>
    </tr>
</c:forEach>

If you are here to copy-paste code:

This is an example which removes node_modules from history

git filter-branch --tree-filter "rm -rf node_modules" --prune-empty HEAD
git for-each-ref --format="%(refname)" refs/original/ | xargs -n 1 git update-ref -d
echo node_modules/ >> .gitignore
git add .gitignore
git commit -m 'Removing node_modules from git history'
git gc
git push origin master --force

What git actually does:

The first line iterates through all references on the same tree (--tree-filter) as HEAD (your current branch), running the command rm -rf node_modules. This command deletes the node_modules folder (-r, without -r, rm won't delete folders), with no prompt given to the user (-f). The added --prune-empty deletes useless (not changing anything) commits recursively.

The second line deletes the reference to that old branch.

The rest of the commands are relatively straightforward.

Good question with a simple answer: you can't!

Javascript is a client-side programming language, therefore it works on the client's machine, so you can't actually hide anything from the client.
Obfuscating your code is a good solution, but it's not enough, because, although it is hard, someone could decipher your code and "steal" your script.
There are a few ways of making your code hard to be stolen, but as i said nothing is bullet-proof.

Off the top of my head, one idea is to restrict access to your external js files from outside the page you embed your code in. In that case, if you have

<script type="text/javascript" src="myJs.js"></script>

and someone tries to access the myJs.js file in browser, he shouldn't be granted any access to the script source.
For example, if your page is written in php, you can include the script via the include function and let the script decide if it's safe" to return it's source.
In this example, you'll need the external "js" (written in php) file myJs.php :

<?php
    $URL = $_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];
    if ($URL != "my-domain.com/my-page.php")
    die("/\*sry, no acces rights\*/");
?>
// your obfuscated script goes here

that would be included in your main page my-page.php :

<script type="text/javascript">
    <?php include "myJs.php"; ?>;
</script> 

This way, only the browser could see the js file contents.

Another interesting idea is that at the end of your script, you delete the contents of your dom script element, so that after the browser evaluates your code, the code disappears :

<script id="erasable" type="text/javascript">
    //your code goes here
    document.getElementById('erasable').innerHTML = "";
</script>

These are all just simple hacks that cannot, and I can't stress this enough : cannot, fully protect your js code, but they can sure piss off someone who is trying to "steal" your code.

Update:

I recently came across a very interesting article written by Patrick Weid on how to hide your js code, and he reveals a different approach: you can encode your source code into an image! Sure, that's not bullet proof either, but it's another fence that you could build around your code.
The idea behind this approach is that most browsers can use the canvas element to do pixel manipulation on images. And since the canvas pixel is represented by 4 values (rgba), each pixel can have a value in the range of 0-255. That means that you can store a character (actual it's ascii code) in every pixel. The rest of the encoding/decoding is trivial.
Thanks, Patrick!

A difference between print and sys.stdout.write to point out in Python 3, is also the value which is returned when executed in the terminal. In Python 3, sys.stdout.write returns the length of the string whereas print returns just None.

So for example running following code interactively in the terminal would print out the string followed by its length, since the length is returned and output when run interactively:

>>> sys.stdout.write(" hi ")
 hi 4

Matplot colors your plot with different colors , but incase you wanna put specific colors

    import matplotlib.pyplot as plt
    import numpy as np
            
    x = np.arange(10)
            
    plt.plot(x, x)
    plt.plot(x, 2 * x,color='blue')
    plt.plot(x, 3 * x,color='red')
    plt.plot(x, 4 * x,color='green')
    plt.show()

You can use the document's import (or adopt) method to add XML fragments:

  /**
   * @param docBuilder
   *          the parser
   * @param parent
   *          node to add fragment to
   * @param fragment
   *          a well formed XML fragment
   */
  public static void appendXmlFragment(
      DocumentBuilder docBuilder, Node parent,
      String fragment) throws IOException, SAXException {
    Document doc = parent.getOwnerDocument();
    Node fragmentNode = docBuilder.parse(
        new InputSource(new StringReader(fragment)))
        .getDocumentElement();
    fragmentNode = doc.importNode(fragmentNode, true);
    parent.appendChild(fragmentNode);
  }

Try JScrambler. I gave it a spin recently and was impressed by it. It provides a set of templates for obfuscation with predefined settings for those who don't care much about the details and just want to get it done quickly. You can also create custom obfuscation by choosing whatever transformations/techniques you want.

Option 1 - Android PCAP

Limitation

Android PCAP should work so long as:

Your device runs Android 4.0 or higher (or, in theory, the few devices which run Android 3.2). Earlier versions of Android do not have a USB Host API

Option 2 - TcpDump

Limitation

Phone should be rooted

Option 3 - bitshark (I would prefer this)

Limitation

Phone should be rooted

Reason - the generated PCAP files can be analyzed in WireShark which helps us in doing the analysis.

Other Options without rooting your phone

1. tPacketCapture

https://play.google.com/store/apps/details?id=jp.co.taosoftware.android.packetcapture&hl=en

Advantages

Using tPacketCapture is very easy, captured packet save into a PCAP file that can be easily analyzed by using a network protocol analyzer application such as Wireshark.

2. You can route your android mobile traffic to PC and capture the traffic in the desktop using any network sniffing tool.

I found one way to access the shared folder without giving the username and password.

We need to change the share folder protect settings in the machine where the folder has been shared.

Go to Control Panel > Network and sharing center > Change advanced sharing settings > Enable Turn Off password protect sharing option.

By doing the above settings we can access the shared folder without any username/password.

If margin is low, then it is always better to start with new plotting device:

dev.new()
# plot()
# save your plot
dev.off()

You will never get margin error, unless you plot something large which can not be accommodated.

FWIW, on Ubuntu 10.04.2 LTS installing the ca-certificates-java and the ca-certificates packages fixed this problem for me.

If you clone with the --depth parameter, it sets .git/config not to fetch all branches, but only master.

You can simply omit the parameter or update the configuration file from

fetch = +refs/heads/master:refs/remotes/origin/master

to

fetch = +refs/heads/*:refs/remotes/origin/*

Task

Extract substring between two string (excluding this two strings)

Solution

let allText = "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum";
let textBefore = "five centuries,";
let textAfter = "electronic typesetting";
var regExp = new RegExp(`(?<=${textBefore}\\s)(.+?)(?=\\s+${textAfter})`, "g");
var results = regExp.exec(allText);
if (results && results.length > 1) {
    console.log(results[0]);
}

Below worked for me,

- name: Ansible delete html directory
  file:
   path: /var/www/html
   state: directory

You could do something like this, based on the ascii values of the characters:

char[26] alphabet;

for(int i = 0; i <26; i++)
{
     alphabet[i] = (char)(i+65); //65 is the offset for capital A in the ascaii table
}

(See the table here.) You are just casting from the int value of the character to the character value - but, that only works for ascii characters not different languages etc.

EDIT: As suggested by Mehrdad in the comment to a similar solution, it's better to do this:

alphabet[i] = (char)(i+(int)('A'));

This casts the A character to it's int value and then increments based on this, so it's not hardcoded.

Use the -s or --strategy option combined with the -X option. In your specific question, you want to keep all of the remote files and replace the local files of the same name.

Replace conflicts with the remote version

git merge -s recursive -Xtheirs upstream/master  

will use the remote repo version of all conflicting files.

Replace conflicts with the local version

git merge -s recursive -Xours upstream/master

will use the local repo version of all conflicting files.

If storing less then 1 mil records, and high performance is not an issue go for varchar(20)/char(20) otherwise I've found that for storing even 100 milion global business phones or personal phones, int is best. Reason : smaller key -> higher read/write speed, also formatting can allow for duplicates.

1 phone in char(20) = 20 bytes vs 8 bytes bigint (or 10 vs 4 bytes int for local phones, up to 9 digits) , less entries can enter the index block => more blocks => more searches, see this for more info (writen for Mysql but it should be true for other Relational Databases).

Here is an example of phone tables:

CREATE TABLE `phoneNrs` (   
    `internationalTelNr` bigint(20) unsigned NOT NULL COMMENT 'full number, no leading 00 or +, up to 19 digits, E164 format',
    `format` varchar(40) NOT NULL COMMENT 'ex: (+NN) NNN NNN NNN, optional',
    PRIMARY KEY (`internationalTelNr`)
    )
DEFAULT CHARSET=ascii
DEFAULT COLLATE=ascii_bin

or with processing/splitting before insert (2+2+4+1 = 9 bytes)

Also "the phone number is not a number", in my opinion is relative to the type of phone numbers. If we're talking of an internal mobile phoneBook, then strings are fine, as the user may wish to store GSM Hash Codes. If storing E164 phones, bigint is the best option.

You get the cursor position by calling GetCursorPos.

POINT p;
if (GetCursorPos(&p))
{
    //cursor position now in p.x and p.y
}

This returns the cursor position relative to screen coordinates. Call ScreenToClient to map to window coordinates.

if (ScreenToClient(hwnd, &p))
{
    //p.x and p.y are now relative to hwnd's client area
}

You hide and show the cursor with ShowCursor.

ShowCursor(FALSE);//hides the cursor
ShowCursor(TRUE);//shows it again

You must ensure that every call to hide the cursor is matched by one that shows it again.

There is Firebug Lite which gives a lot of Firebug functionality in IE.

You should use formControlName="surveyType" on an input and not on a div

As others have already said, parameters passed through the command line can be accessed in batch files with the notation %1 to %9. There are also two other tokens that you can use:

• %0 is the executable (batch file) name as specified in the command line.
• %* is all parameters specified in the command line -- this is very useful if you want to forward the parameters to another program.

There are also lots of important techniques to be aware of in addition to simply how to access the parameters.

Checking if a parameter was passed

This is done with constructs like IF "%~1"=="", which is true if and only if no arguments were passed at all. Note the tilde character which causes any surrounding quotes to be removed from the value of %1; without a tilde you will get unexpected results if that value includes double quotes, including the possibility of syntax errors.

Handling more than 9 arguments (or just making life easier)

If you need to access more than 9 arguments you have to use the command SHIFT. This command shifts the values of all arguments one place, so that %0 takes the value of %1, %1 takes the value of %2, etc. %9 takes the value of the tenth argument (if one is present), which was not available through any variable before calling SHIFT (enter command SHIFT /? for more options).

SHIFT is also useful when you want to easily process parameters without requiring that they are presented in a specific order. For example, a script may recognize the flags -a and -b in any order. A good way to parse the command line in such cases is

:parse
IF "%~1"=="" GOTO endparse
IF "%~1"=="-a" REM do something
IF "%~1"=="-b" REM do something else
SHIFT
GOTO parse
:endparse
REM ready for action!

This scheme allows you to parse pretty complex command lines without going insane.

Substitution of batch parameters

For parameters that represent file names the shell provides lots of functionality related to working with files that is not accessible in any other way. This functionality is accessed with constructs that begin with %~.

For example, to get the size of the file passed in as an argument use

ECHO %~z1

To get the path of the directory where the batch file was launched from (very useful!) you can use

ECHO %~dp0

You can view the full range of these capabilities by typing CALL /? in the command prompt.

User Endless is right,

$.browser.chrome = (typeof window.chrome === "object"); 

code is best to detect Chrome browser using jQuery.

If you using IE and added GoogleFrame as plugin then

var is_chrome = /chrome/.test( navigator.userAgent.toLowerCase() );

code will treat as Chrome browser because GoogleFrame plugin modifying the navigator property and adding chromeframe inside it.

There are many other reasons. You should always initialize all member variables in the initialization list if possible.

Add a type="search" to your input
The support is pretty decent but will not work in IE<10

<input type="search">

Older browsers

If you need IE9 support here are some workarounds

Using a standard <input type="text"> and some HTML elements:

/**
 * Clearable text inputs
 */
$(".clearable").each(function() {
  
  const $inp = $(this).find("input:text"),
      $cle = $(this).find(".clearable__clear");

  $inp.on("input", function(){
    $cle.toggle(!!this.value);
  });
  
  $cle.on("touchstart click", function(e) {
    e.preventDefault();
    $inp.val("").trigger("input");
  });
  
});

/* Clearable text inputs */
.clearable{
  position: relative;
  display: inline-block;
}
.clearable input[type=text]{
  padding-right: 24px;
  width: 100%;
  box-sizing: border-box;
}
.clearable__clear{
  display: none;
  position: absolute;
  right:0; top:0;
  padding: 0 8px;
  font-style: normal;
  font-size: 1.2em;
  user-select: none;
  cursor: pointer;
}
.clearable input::-ms-clear {  /* Remove IE default X */
  display: none;
}

<span class="clearable">
  <input type="text" name="" value="" placeholder="">
  <i class="clearable__clear">&times;</i>
</span>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>

Using only a <input class="clearable" type="text"> (No additional elements)

set a class="clearable" and play with it's background image:

/**
 * Clearable text inputs
 */
function tog(v){return v ? "addClass" : "removeClass";} 
$(document).on("input", ".clearable", function(){
    $(this)[tog(this.value)]("x");
}).on("mousemove", ".x", function( e ){
    $(this)[tog(this.offsetWidth-18 < e.clientX-this.getBoundingClientRect().left)]("onX");
}).on("touchstart click", ".onX", function( ev ){
    ev.preventDefault();
    $(this).removeClass("x onX").val("").change();
});

// $('.clearable').trigger("input");
// Uncomment the line above if you pre-fill values from LS or server

/*
    Clearable text inputs
*/
.clearable{
  background: #fff url(http://i.stack.imgur.com/mJotv.gif) no-repeat right -10px center;
  border: 1px solid #999;
  padding: 3px 18px 3px 4px; /* Use the same right padding (18) in jQ! */
  border-radius: 3px;
  transition: background 0.4s;
}
.clearable.x  { background-position: right 5px center; } /* (jQ) Show icon */
.clearable.onX{ cursor: pointer; } /* (jQ) hover cursor style */
.clearable::-ms-clear {display: none; width:0; height:0;} /* Remove IE default X */

<input class="clearable" type="text" name="" value="" placeholder="" />

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>

The trick is to set some right padding (I used 18px) to the input and push the background-image right, out of sight (I used right -10px center).
That 18px padding will prevent the text hide underneath the icon (while visible).
jQuery will add the class "x" (if input has value) showing the clear icon.
Now all we need is to target with jQ the inputs with class x and detect on mousemove if the mouse is inside that 18px "x" area; if inside, add the class onX.
Clicking the onX class removes all classes, resets the input value and hides the icon.

I was using DOCKER_OPTS="--dns 8.8.8.8" and later discovered and that my container didn't have direct access to internet but could access my corporate intranet. I changed DOCKER_OPTS to the following:

DOCKER_OPTS="--dns <internal_corporate_dns_address"

replacing internal_corporate_dns_address with the IP address or FQDN of our DNS and restarted docker using

sudo service docker restart

and then spawned my container and checked that it had access to internet.

arr[title] = link;

You're not pushing into the array, you're setting the element with the key title to the value link. As such your array should be an object.

git pull origin master

this will sync your master to the central repo and if new branches are pushed to the central repo it will also update your clone copy.

It is still under development but you can already use jHardware

It is a simple library that scraps system data using Java. It works in both Linux and Windows.

ProcessorInfo info = HardwareInfo.getProcessorInfo();
//Get named info
System.out.println("Cache size: " + info.getCacheSize());        
System.out.println("Family: " + info.getFamily());
System.out.println("Speed (Mhz): " + info.getMhz());
//[...]

Google eventually came up with the answer. The syntax for string replacement in batch is this:

set v_myvar=replace me
set v_myvar=%v_myvar:ace=icate%

Which produces "replicate me". My script now looks like this:

@echo off
set v_params=%*
set v_params=%v_params:"=\"%
call bash -c "g++-linux-4.1 %v_params%"

Which replaces all instances of " with \", properly escaped for bash.

There is also Mappa - http://mappatool.com/.

It only supports polygons, but they are definitely the hardest parts :)

public static int convBool(boolean b)
{
int convBool = 0;
if(b) convBool = 1;

Then use :

On Mac IntelliJ Idea 12 has it's preferences/keymaps placed here: ./Users/viliuskraujutis/Library/Preferences/IdeaIC12/keymaps/

Just doing like @Kjartan.

Steps are as follows:

1. Right click your C# project name in Visual Studio's "Solution Explorer";

2. Then, select "add -> Reference -> COM -> Type Libraries " in order;

3. Find the "Microsoft Office 16.0 Object Library", and add it to reference (Note: the version number may vary with the OFFICE you have installed);

4. After doing this, you will see "Microsoft.Office.Interop.Word" under the "Reference" item in your project.

Normally a wart to indicate the type is appended or prepended to the name. You can get away with macros is some instances, but it rather depends what you're trying to do. There's no polymorphism in C, only coercion.

Simple generic operations can be done with macros:

#define max(x,y) ((x)>(y)?(x):(y))

If your compiler supports typeof, more complicated operations can be put in the macro. You can then have the symbol foo(x) to support the same operation different types, but you can't vary the behaviour between different overloads. If you want actual functions rather than macros, you might be able to paste the type to the name and use a second pasting to access it (I haven't tried).

In Python 3, you can only print as:

print("STRING")

But in Python 2, the parentheses are not necessary.

In general, that's not how systems use GET requests. So, it will be hard to get your libraries to play along. In fact, the spec says that "If the request method is a case-sensitive match for GET or HEAD act as if data is null." So, I think you are out of luck unless the browser you are using doesn't respect that part of the spec.

You can probably setup an endpoint on your own server for a POST ajax request, then redirect that in your server code to a GET request with a body.

If you aren't absolutely tied to GET requests with the body being the data, you have two options.

POST with data: This is probably what you want. If you are passing data along, that probably means you are modifying some model or performing some action on the server. These types of actions are typically done with POST requests.

GET with query string data: You can convert your data to query string parameters and pass them along to the server that way.

url: 'somesite.com/models/thing?ids=1,2,3'

../ takes you one folder up the directory tree. Then, select the appropriate folder and its contents.

../images/logo.png

my choice was to add a td between the two td tags and set the width to 25px. It can be more or less to your liking. This may be cheesy but it is simple and it works.

Initial answer from 2013

If you don't mind something related to Bootstrap, an excellent (unofficial) Bootstrap Switch is available.

It uses radio types or checkboxes as switches. A type attribute has been added since V.1.8.

Source code is available on Github.

Note from 2018

I would not recommend to use those kind of old Switch buttons now, as they always seemed to suffer of usability issues as pointed by many people.

Please consider having a look at modern Switches like those.

There are CSS options for the audio tag.

Like: html 5 audio tag width

But if you play around with it you'll see results can be unexpected - as of August 2012.

You can use like this

let nsRange = NSRange(location: someInt, length: someInt)

as in

let myNSString = bigTOTPCode as NSString //12345678
let firstDigit = myNSString.substringWithRange(NSRange(location: 0, length: 1)) //1
let secondDigit = myNSString.substringWithRange(NSRange(location: 1, length: 1)) //2
let thirdDigit = myNSString.substringWithRange(NSRange(location: 2, length: 4)) //3456

Both of these usages can be applied:

// more compact, and colour can be applied (better for process managers logging)
console.dir(queryArgs, { depth: null, colors: true });

// get a clear list of actual values
console.log(JSON.stringify(queryArgs, undefined, 2));

From the Rails api on PartialRender:

Rendering the default case

If you're not going to be using any of the options like collections or layouts, you can also use the short-hand defaults of render to render partials.

Examples:

# Instead of <%= render partial: "account" %>
<%= render "account" %>

# Instead of <%= render partial: "account", locals: { account: @buyer } %>
<%= render "account", account: @buyer %>

# @account.to_partial_path returns 'accounts/account', so it can be used to replace:
# <%= render partial: "accounts/account", locals: { account: @account} %>
<%= render @account %>

# @posts is an array of Post instances, so every post record returns 'posts/post' on `to_partial_path`,
# that's why we can replace:
# <%= render partial: "posts/post", collection: @posts %>
<%= render @posts %>

So, you can use pass a local variable size to render as follows:

<%= render @users, size: 50 %>

and then use it in the _user.html.erb partial:

<li>
    <%= gravatar_for user, size: size %>
    <%= link_to user.name, user %>
</li>

Note that size: size is equivalent to :size => size.

I think it would be interesting to write both of them in a way that only by switching some lines of code would give you one algorithm or the other, so that you will see that your dillema is not so strong as it seems to be at first.

I personally like the interpretation of BFS as flooding a landscape: the low altitude areas will be flooded first, and only then the high altitude areas would follow. If you imagine the landscape altitudes as isolines as we see in geography books, its easy to see that BFS fills all area under the same isoline at the same time, just as this would be with physics. Thus, interpreting altitudes as distance or scaled cost gives a pretty intuitive idea of the algorithm.

With this in mind, you can easily adapt the idea behind breadth first search to find the minimum spanning tree easily, shortest path, and also many other minimization algorithms.

I didnt see any intuitive interpretation of DFS yet (only the standard one about the maze, but it isnt as powerful as the BFS one and flooding), so for me it seems that BFS seems to correlate better with physical phenomena as described above, while DFS correlates better with choices dillema on rational systems (ie people or computers deciding which move to make on a chess game or going out of a maze).

So, for me the difference between lies on which natural phenomenon best matches their propagation model (transversing) in real life.

Although you ask about numpy arrays, you can get the same behavior for regular Python lists by using operator.itemgetter.

>>> from operator import itemgetter
>>> a = [0,88,26,3,48,85,65,16,97,83,91]
>>> ind_pos = [1, 5, 7]
>>> print itemgetter(*ind_pos)(a)
(88, 85, 16)

You can use pydoc.

Open your terminal and type python -m pydoc list.append

The advantage of pydoc over help() is that you do not have to import a module to look at its help text. For instance python -m pydoc random.randint.

Also you can start an HTTP server to interactively browse documentation by typing python -m pydoc -b (python 3)

For more information python -m pydoc

When you do : f.readlines() you already read all the file so f.tell() will show you that you are in the end of the file, and doing f.next() will result in a StopIteration error.

Alternative of what you want to do is:

filne = "D:/testtube/testdkanimfilternode.txt"

with open(filne, 'r+') as f:
    for line in f:
        if line.startswith("anim "):
            print f.next() 
            # Or use next(f, '') to return <empty string> instead of raising a  
            # StopIteration if the last line is also a match.
            break

Use the "form" attribute, if you want to save your markup:

<form method="GET" id="my_form"></form>

<table>
    <tr>
        <td>
            <input type="text" name="company" form="my_form" />
            <button type="button" form="my_form">ok</button>
        </td>
    </tr>
</table>

(*Form fields outside of the < form > tag)

You have a couple of options:

• You can add the path to the DLLs to the Executable files settings under Tools > Options > Projects and Solutions > VC++ Directories (but only for building, for executing or debugging here)
• You can add them in your global PATH environment variable
• You can start Visual Studio using a batch file as I described here and manipulate the path in that one
• You can copy the DLLs into the executable file's directory :-)

If your data contains any newlines or commas, you will need to escape those first:

const escape = text =>
    text.replace(/\\/g, "\\\\")
        .replace(/\n/g, "\\n")
        .replace(/,/g, "\\,")

escaped_array = test_array.map(fields => fields.map(escape))

Then simply do:

csv = escaped_array.map(fields => fields.join(","))
                .join("\n")

If you want to make it downloadable in-browser:

dl = "data:text/csv;charset=utf-8," + csv
window.open(encodeURI(dl))

You start tomcat from some directory - which is the $cwd for tomcat. You can specify any path relative to this $cwd.

suppose you have

home
- tomcat
 |_bin
- cssStore
 |_file.css

And suppose you start tomcat from ~/tomcat, using the command "bin/startup.sh".

~/tomcat becomes the home directory ($cwd) for tomcat

You can access "../cssStore/file.css" from class files in your servlet now

Hope that helps, - M.S.

Visual Studio 2013: Yes to both adding to the watch windows during debugging and dragging variables or typing them in without "user::". But before any of that would work I also needed to go to Tools > Options, then Debugging > General and had to scroll right down to the bottom of the right hand pane to be able to tick "Use Managed Compatibility Mode". Then I had to stop and restart debugging. Finally the above advice worked. Many thanks to the above and to this article: Visual Studio 2015 Debugging: Can't expand local variables?

Mozilla's MDN suggests something like the following [source]:

This answer is for beginners (none-git gurus). I recently had this problem and maybe its just me but most of the answers seemed to require rather advance understanding of git. After reading several stack overflow answers including this thread, here are the steps I needed to take in order to easily switch between GitHub accounts (e.g. assume two GitHub accounts, github.com/personal and gitHub.com/work):

1. Check for existing ssh keys: Open Terminal and run this command to see/list existing ssh keys ls -al ~/.ssh
   files with extension .pub are your ssh keys so you should have two for the personal and work accounts. If there is only one or none, its time to generate other wise skip this.
   
   - Generating ssh key: login to github (either the personal or work acc.), navigate to Settings and copy the associated email.
   now go back to Terminal and run ssh-keygen -t rsa -C "the copied email", you'll see:
   
   Generating public/private rsa key pair.
   Enter file in which to save the key (/.../.ssh/id_rsa):
   
   id_rsa is the default name for the soon to be generated ssh key so copy the path and rename the default, e.g. /.../.ssh/id_rsa_work if generating for work account. provide a password or just enter to ignore and, you'll read something like The key's randomart image is: and the image. done.
   Repeat this step once more for your second github account. Make sure you use the right email address and a different ssh key name (e.g. id_rsa_personal) to avoid overwriting.
   At this stage, you should see two ssh keys when running ls -al ~/.ssh again.
2. Associate ssh key with gitHub account: Next step is to copy one of the ssh keys, run this but replacing your own ssh key name: pbcopy < ~/.ssh/id_rsa_work.pub, replace id_rsa_work.pub with what you called yours.
   Now that our ssh key is copied to clipboard, go back to github account [Make sure you're logged in to work account if the ssh key you copied is id_rsa_work] and navigate to
   Settings - SSH and GPG Keys and click on New SSH key button (not New GPG key btw :D)
   give some title for this key, paste the key and click on Add SSH key. You've now either successfully added the ssh key or noticed it has been there all along which is fine (or you got an error because you selected New GPG key instead of New SSH key :D).
3. Associate ssh key with gitHub account: Repeat the above step for your second account.

4. Edit the global git configuration: Last step is to make sure the global configuration file is aware of all github accounts (so to say).
   Run git config --global --edit to edit this global file, if this opens vim and you don't know how to use it, press i to enter Insert mode, edit the file as below, and press esc followed by :wq to exit insert mode:

   [inside this square brackets give a name to the followed acc.] name = github_username email = github_emailaddress [any other name] name = github_username email = github_email [credential] helper = osxkeychain useHttpPath = true

Done!, now when trying to push or pull from a repo, you'll be asked which GitHub account should be linked with this repo and its asked only once, the local configuration will remember this link and not the global configuration so you can work on different repos that are linked with different accounts without having to edit global configuration each time.

To force the download of a PDF file, instead of being handled by the browser's PDF plugin:

public ActionResult DownloadPDF()
{
    return File("~/Content/MyFile.pdf", "application/pdf", "MyRenamedFile.pdf");
}

If you want to let the browser handle by its default behavior (plugin or download), just send two parameters.

public ActionResult DownloadPDF()
{
    return File("~/Content/MyFile.pdf", "application/pdf");
}

You'll need to use the third parameter to specify a name for the file on the browser dialog.

UPDATE: Charlino is right, when passing the third parameter (download filename) Content-Disposition: attachment; gets added to the Http Response Header. My solution was to send application\force-download as the mime-type, but this generates a problem with the filename of the download so the third parameter is required to send a good filename, therefore eliminating the need to force a download.

It's because you have turned on USB debugging in Developer Options. You can create a bug report by holding the power + both volume up and down.

Edit: This is what the forums say:

By pressing Volume up + Volume down + power button, you will feel a vibration after a second or so, that's when the bug reporting initiated.

1. Download the package
2. unzip it if it is zipped
3. cd into the directory containing setup.py
4. If there are any installation instructions contained in documentation contianed herein, read and follow the instructions OTHERWISE
5. type in python setup.py install

You may need administrator privileges for step 5. What you do here thus depends on your operating system. For example in Ubuntu you would say sudo python setup.py install

EDIT- thanks to kwatford (see first comment)

To bypass the need for administrator privileges during step 5 above you may be able to make use of the --user flag. In this way you can install the package only for the current user.

The docs say:

Files will be installed into subdirectories of site.USER_BASE (written as userbase hereafter). This scheme installs pure Python modules and extension modules in the same location (also known as site.USER_SITE). Here are the values for UNIX, including Mac OS X:

More details can be found here: http://docs.python.org/2.7/install/index.html

There is not a way to directly get the version out, but there are two work-arounds that could be done.

1. The version could be stored in a resource string, and placed into the manifest by:

   <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.somepackage"
        android:versionName="@string/version" android:versionCode="20">
   

2. One could create a custom view, and place it into the XML. The view would use this to assign the name:

   context.getPackageManager().getPackageInfo(context.getPackageName(), 0).versionName;
   

Either of these solutions would allow for placing the version name in XML. Unfortunately there isn't a nice simple solution, like android.R.string.version or something like that.

Not sure if Access supports it, but in most engines (including SQL Server) this is called a correlated subquery and works fine:

SELECT  TypesAndBread.Type, TypesAndBread.TBName,
        (
        SELECT  Count(Sandwiches.[SandwichID]) As SandwichCount
        FROM    Sandwiches
        WHERE   (Type = 'Sandwich Type' AND Sandwiches.Type = TypesAndBread.TBName)
                OR (Type = 'Bread' AND Sandwiches.Bread = TypesAndBread.TBName)
        ) As SandwichCount
FROM    TypesAndBread

This can be made more efficient by indexing Type and Bread and distributing the subqueries over the UNION:

SELECT  [Sandwiches Types].[Sandwich Type] As TBName, "Sandwich Type" As Type,
        (
        SELECT  COUNT(*) As SandwichCount
        FROM    Sandwiches
        WHERE   Sandwiches.Type = [Sandwiches Types].[Sandwich Type]
        )
FROM    [Sandwiches Types]
UNION ALL
SELECT  [Breads].[Bread] As TBName, "Bread" As Type,
        (
        SELECT  COUNT(*) As SandwichCount
        FROM    Sandwiches
        WHERE   Sandwiches.Bread = [Breads].[Bread]
        )
FROM    [Breads]

• One simple way is replace \n(newline) with ","(double-quote comma double-quote) after this append double-quote in the start and end of file.

example:

      AliceBlue
      AntiqueWhite
      Aqua
      Aquamarine
      Beige

• Replcae \n with ","

    AliceBlue","AntiqueWhite","Aqua","Aquamarine","Beige
  

• Now append "(double-quote) at the start and end

   "AliceBlue","AntiqueWhite","Aqua","Aquamarine","Beige"
  

If your text contains blank lines in between you can use regular expression \n+ instead of \n

example:

      AliceBlue

      AntiqueWhite
      Aqua


      Aquamarine
      Beige

• Replcae \n+ with "," (in regex mode)

    AliceBlue","AntiqueWhite","Aqua","Aquamarine","Beige
  

• Now append "(double-quote) at the start and end

   "AliceBlue","AntiqueWhite","Aqua","Aquamarine","Beige"
  

Highly recommend using a handler to handle the response.

client.execute(yourRequest,defaultHanler);

It will release the connection automatically with consume(HTTPENTITY) method.

A handler example:

private ResponseHandler<String> defaultHandler = new ResponseHandler<String>() {
    @Override
    public String handleResponse(HttpResponse response)
        throws IOException {
        int status = response.getStatusLine().getStatusCode();

        if (status >= 200 && status < 300) {
            HttpEntity entity = response.getEntity();
            return entity != null ? EntityUtils.toString(entity) : null;
        } else {
            throw new ClientProtocolException("Unexpected response status: " + status);
        }
    }
};

I was looking for something and I found this post. I post this code that managed many-to-many relationships in case someone needs it.

    var UserInRole = db.UsersInRoles.Include(u => u.UserProfile).Include(u => u.Roles)
    .Select (m => new 
    {
        UserName = u.UserProfile.UserName,
        RoleName = u.Roles.RoleName
    });

I had the same problem and needed to restart the cmd - and the problem goes away.

Why not just try loading all the files in the folder? If OpenCV can't open it, oh well. Move on to the next. cv2.imread() returns None if the image can't be opened. Kind of weird that it doesn't raise an exception.

import cv2
import os

def load_images_from_folder(folder):
    images = []
    for filename in os.listdir(folder):
        img = cv2.imread(os.path.join(folder,filename))
        if img is not None:
            images.append(img)
    return images

To customize markers, you can do it from this online tool: https://materialdesignicons.com/

In your case, you want the map-marker which is available here: https://materialdesignicons.com/icon/map-marker and which you can customize online.

If you simply want to change the default Red color to Blue, you can load this icon: http://maps.google.com/mapfiles/ms/icons/blue-dot.png

Ahem...

The short answer to your question is that you must set the height of 100% to the body and html tag, then set the height to 100% on each div element you want to make 100% the height of the page.

Actually, 100% height will not work in most design situations - this may be short but it is not a good answer. Google "any column longest" layouts. The best way is to put the left and right cols inside a wrapper div, float the left and right cols and then float the wrapper - this makes it stretch to the height of the inner containers - then set background image on the outer wrapper. But watch for any horizontal margins on the floated elements in case you get the IE "double margin float bug".

Worked for me only when path was set, i.e.:

$.cookie('name', null, {path:'/'})

I was running into the same issue, and what I was missing in my setup was including this in my maven (pom.xml) file.

<dependency>
     <groupId>org.codehaus.jackson</groupId>
     <artifactId>jackson-mapper-asl</artifactId>
     <version>1.9.9</version>
</dependency> 

The straight up answer to your question is: No. The signature for the PostAsync method is as follows:

public Task PostAsync(Uri requestUri, HttpContent content)

So, while you can pass an object to PostAsync it must be of type HttpContent and your anonymous type does not meet that criteria.

However, there are ways to accomplish what you want to accomplish. First, you will need to serialize your anonymous type to JSON, the most common tool for this is Json.NET. And the code for this is pretty trivial:

var myContent = JsonConvert.SerializeObject(data);

Next, you will need to construct a content object to send this data, I will use a ByteArrayContent object, but you could use or create a different type if you wanted.

var buffer = System.Text.Encoding.UTF8.GetBytes(myContent);
var byteContent = new ByteArrayContent(buffer);

Next, you want to set the content type to let the API know this is JSON.

byteContent.Headers.ContentType = new MediaTypeHeaderValue("application/json");

Then you can send your request very similar to your previous example with the form content:

var result = client.PostAsync("", byteContent).Result

On a side note, calling the .Result property like you're doing here can have some bad side effects such as dead locking, so you want to be careful with this.

You mean the tellItLikeItIs method? Yes, you have to specify void to specify that the method doesn't return anything. All methods have to have a return type specified, even if it's void.

It certainly doesn't return a string - look, there are no return statements anywhere. It's not really clear why you think it is returning a string. It's printing strings to the console, but that's not the same thing as returning one from the method.

You can generate pairs like this:

{(x, x + 2) for x in r if x + 2 in r}

Then all that is left to do is to get a condition to make them prime, which you have already done in the first example.

A different way of doing it: (Although slower for large sets of primes)

{(x, y) for x in r for y in r if x + 2 == y}

No one probably really wants to remove row one. So if you are looking for something meaningful, that is conditional selection

#remove rows that have long length and "0" value for vector E

>> setNew<-set[!(set$length=="long" & set$E==0),]

I was able to resolve this like so:

$ brew update
$ brew doctor
$ brew uninstall python
$ brew install python --build-from-source    # took ~5 mins
$ python --version                           # => Python 2.7.9
$ pip install --upgrade pip

I'm running w/ the following stuff (as of Jan 2, 2015):

$ brew -v

From the .NET blog Announcing .NET 2015 Preview: A New Era for .NET:

.NET Core has two major components. It includes a small runtime that is built from the same codebase as the .NET Framework CLR. The .NET Core runtime includes the same GC and JIT (RyuJIT), but doesn’t include features like Application Domains or Code Access Security. The runtime is delivered via NuGet, as part of the [ASP.NET Core] package.

.NET Core also includes the base class libraries. These libraries are largely the same code as the .NET Framework class libraries, but have been factored (removal of dependencies) to enable us to ship a smaller set of libraries. These libraries are shipped as System.* NuGet packages on NuGet.org.

And:

[ASP.NET Core] is the first workload that has adopted .NET Core. [ASP.NET Core] runs on both the .NET Framework and .NET Core. A key value of [ASP.NET Core] is that it can run on multiple versions of [.NET Core] on the same machine. Website A and website B can run on two different versions of .NET Core on the same machine, or they can use the same version.

In short: first, there was the Microsoft .NET Framework, which consists of a runtime that executes application and library code, and a nearly fully documented standard class library.

The runtime is the Common Language Runtime, which implements the Common Language Infrastructure, works with The JIT compiler to run the CIL (formerly MSIL) bytecode.

Microsoft's specification and implementation of .NET were, given its history and purpose, very Windows- and IIS-centered and "fat". There are variations with fewer libraries, namespaces and types, but few of them were useful for web or desktop development or are troublesome to port from a legal standpoint.

So in order to provide a non-Microsoft version of .NET, which could run on non-Windows machines, an alternative had to be developed. Not only the runtime has to be ported for that, but also the entire Framework Class Library to become well-adopted. On top of that, to be fully independent from Microsoft, a compiler for the most commonly used languages will be required.

Mono is one of few, if not the only alternative implementation of the runtime, which runs on various OSes besides Windows, almost all namespaces from the Framework Class Library as of .NET 4.5 and a VB and C# compiler.

Enter .NET Core: an open-source implementation of the runtime, and a minimal base class library. All additional functionality is delivered through NuGet packages, deploying the specific runtime, framework libraries and third-party packages with the application itself.

ASP.NET Core is a new version of MVC and WebAPI, bundled together with a thin HTTP server abstraction, that runs on the .NET Core runtime - but also on the .NET Framework.

$num = array (0 => array ('id' => '20110209172713', 'Date' => '2011-02-09', 'Weight' => '200'),
          1 => array ('id' => '20110209172747', 'Date' => '2011-02-09', 'Weight' => '180'),
          2 => array ('id' => '20110209172827', 'Date' => '2011-02-09', 'Weight' => '175'),
          3 => array ('id' => '20110211204433', 'Date' => '2011-02-11', 'Weight' => '195'));

    foreach($num as $key => $val)   
    {                       
        $weight[] = $val['Weight'];
    }

     echo max($weight);
     echo min($weight);

In my own case, i had to set backdrop and set the top and left properties before i could apply draggable function on the modal dialog. Maybe it might help someone ;)

if (!($('.modal.in').length)) {       
$('.modal-dialog').css({
     top: 0,
     left: 0
   });
}
$('#myModal').modal({
  backdrop: false,
   show: true
});

$('.modal-dialog').draggable({
  handle: ".modal-header"
});

You say you don't want to use the system("pause") hack. Why not?

If it's because you don't want the program to prompt when it's not being debugged, there's a way around that. This works for me:

void pause () {
    system ("pause");
}

int main (int argc, char ** argv) {
    // If "launched", then don't let the console close at the end until
    // the user has seen the report.
    // (See the MSDN ConGUI sample code)
    //
    do {
        HANDLE hConsoleOutput = ::GetStdHandle (STD_OUTPUT_HANDLE);
        if (INVALID_HANDLE_VALUE == hConsoleOutput)
            break;
        CONSOLE_SCREEN_BUFFER_INFO csbi;
        if (0 == ::GetConsoleScreenBufferInfo (hConsoleOutput, &csbi))
            break;
        if (0 != csbi.dwCursorPosition.X)
            break;
        if (0 != csbi.dwCursorPosition.Y)
            break;
        if (csbi.dwSize.X <= 0)
            break;
        if (csbi.dwSize.Y <= 0)
            break;
        atexit (pause);
    } while (0);

I just paste this code into each new console application I'm writing. If the program is being run from a command window, the cursor position won't be <0,0>, and it won't call atexit(). If it has been launched from you debugger (any debugger) the console cursor position will be <0,0> and the atexit() call will be executed.

I got the idea from a sample program that used to be in the MSDN library, but I think it's been deleted.

NOTE: The Microsoft Visual Studio implementation of the system() routine requires the COMSPEC environment variable to identify the command line interpreter. If this environment variable gets messed up -- for example, if you've got a problem in the Visual Studio project's debugging properties so that the environment variables aren't properly passed down when the program is launched -- then it will just fail silently.

pipdeptree is a command line utility for displaying the python packages installed in an virtualenv in form of a dependency tree. Just use it: https://github.com/naiquevin/pipdeptree

The answers here work for just 2 cells, but as soon as those columns have more in them it can lead to a bit more complexity. I think I've found a generalized solution for any number of cells in multiple columns.

#Goals Get a vertical sequence of tags on mobile to arrange themselves in whatever order the design calls for on tablet/desktop. In this concrete example, one tag must enter flow earlier than it normally would, and another later than it normally would.

##Mobile

[1 headline]
[2 image]
[3 qty]
[4 caption]
[5 desc]

##Tablet+

[2 image  ][1 headline]
[         ][3 qty     ]
[         ][5 desc    ]
[4 caption][          ]
[         ][          ]

So headline needs to shuffle right on tablet+, and technically, so does desc - it sits above the caption tag that precedes it on mobile. You'll see in a moment 4 caption is in trouble too.

Let's assume every cell could vary in height, and needs to be flush top-to-bottom with its next cell (ruling out weak tricks like a table).

As with all Bootstrap Grid problems step 1 is to realize the HTML has to be in mobile-order, 1 2 3 4 5, on the page. Then, determine how to get tablet/desktop to reorder itself in this way - ideally without Javascript.

The solution to get 1 headline and 3 qty to sit to the right not the left is to simply set them both pull-right. This applies CSS float: right, meaning they find the first open space they'll fit to the right. You can think of the browser's CSS processor working in the following order: 1 fits in to the right top corner. 2 is next and is regular (float: left), so it goes to top-left corner. Then 3, which is float: right so it leaps over underneath 1.

But this solution wasn't enough for 4 caption; because the right 2 cells are so short 2 image on the left tends to be longer than the both of them combined. Bootstrap Grid is a glorified float hack, meaning 4 caption is float: left. With 2 image occupying so much room on the left, 4 caption attempts to fit in the next available space - often the right column, not the left where we wanted it.

The solution here (and more generally for any issue like this) was to add a hack tag, hidden on mobile, that exists on tablet+ to push caption out, that then gets covered up by a negative margin - like this:

[2 image  ][1 headline]
[         ][3 qty     ]
[         ][4 hack    ]
[5 caption][6 desc ^^^]
[         ][          ]

http://jsfiddle.net/b9chris/52VtD/16633/

HTML:

<div id=headline class="col-xs-12 col-sm-6 pull-right">Product Headline</div>
<div id=image class="col-xs-12 col-sm-6">Product Image</div>
<div id=qty class="col-xs-12 col-sm-6 pull-right">Qty, Add to cart</div>
<div id=hack class="hidden-xs col-sm-6">Hack</div>
<div id=caption class="col-xs-12 col-sm-6">Product image caption</div>
<div id=desc class="col-xs-12 col-sm-6 pull-right">Product description</div>

CSS:

#hack { height: 50px; }

@media (min-width: @screen-sm) {
    #desc { margin-top: -50px; }
}

So, the generalized solution here is to add hack tags that can disappear on mobile. On tablet+ the hack tags allow displayed tags to appear earlier or later in the flow, then get pulled up or down to cover up those hack tags.

Note: I've used fixed heights for the sake of the simple example in the linked jsfiddle, but the actual site content I was working on varies in height in all 5 tags. It renders properly with relatively large variance in tag heights, especially image and desc.

Note 2: Depending on your layout, you may have a consistent enough column order on tablet+ (or larger resolutions), that you can avoid use of hack tags, using margin-bottom instead, like so:

Note 3: This uses Bootstrap 3. Bootstrap 4 uses a different grid set, and won't work with these examples.

All you have to do is enable the html variable to true.. I had same issue, all i had to do was html : true ,

    var hh = "<b>test</b>"; 
swal({
        title: "" + txt + "", 
        text: "Testno  sporocilo za objekt " + hh + "",  
        html: true,  
        confirmButtonText: "V redu", 
        allowOutsideClick: "true"  
});

Note: html : "Testno sporocilo za objekt " + hh + "",
may not work as html porperty is only use to active this feature by assign true / false value in the Sweetalert.
this html : "Testno sporocilo za objekt " + hh + "", is used in SweetAlert2

You CAN include a modal within a form. In the Bootstrap documentation it recommends the modal to be a "top level" element, but it still works within a form.

You create a form, and then the modal "save" button will be a button of type="submit" to submit the form from within the modal.

<form asp-action="AddUsersToRole" method="POST" class="mb-3">

You can post (or GET) your form data to any URL. By default it is the serving page URL, but you can change it by setting the form action. You do not have to use ajax.

The solution given by man 3 rand for a number between 1 and 10 inclusive is:

j = 1 + (int) (10.0 * (rand() / (RAND_MAX + 1.0)));

In your case, it would be:

j = min + (int) ((max-min+1) * (rand() / (RAND_MAX + 1.0)));

Of course, this is not perfect randomness or uniformity as some other messages are pointing out, but this is enough for most cases.

the answers above were confusing to me. Here is what i did:

• File ->new Image Asset

• the first field "Asset type" must be launcher icons. browse to the file you want as icon, select it and android studio will show you in the same window what it will look like under different resolutions.

• choose a different name for it, click next. Now the icon set for all those hdpi, xhdpi, mdpi will be in corresponding mipmap folders

• finally, most importantly go to your manifest file and change "android:icon" to the name of your new icon image.

I use proxychains ssh user@host; from proxychains-ng (see https://github.com/rofl0r/proxychains-ng).
By default it uses a socks4 proxy at 127.0.0.1:9050 but it can be changed in the conf file /etc/proxychains.conf or you can specify another conf file proxychains -f custom.conf

The number of inversions in an array is half the total distance elements must be moved in order to sort the array. Therefore, it can be computed by sorting the array, maintaining the resulting permutation p[i], and then computing the sum of abs(p[i]-i)/2. This takes O(n log n) time, which is optimal.

An alternative method is given at http://mathworld.wolfram.com/PermutationInversion.html. This method is equivalent to the sum of max(0, p[i]-i), which is equal to the sum of abs(p[i]-i])/2 since the total distance elements move left is equal to the total distance elements move to the right.

EDIT: This method is wrong (see comments), and there is unfortunately no way to fix it while preserving the character of the method.

i'd just do a simple check to see if d[a] exists and if not initialize it...

var a = "1",
    b = "hello",
    c = { "100" : "some important data" },
    d = {};

    if (d[a] === undefined) {
        d[a] = {}
    };
    d[a]["greeting"] = b;
    d[a]["data"] = c;

    console.debug (d);

For simple situations like the exact example in the OP, I agree that Thierry's answer is the best. However, I think it's useful to point out another approach that becomes easier when you're trying to maintain consistent color schemes across multiple data frames that are not all obtained by subsetting a single large data frame. Managing the factors levels in multiple data frames can become tedious if they are being pulled from separate files and not all factor levels appear in each file.

One way to address this is to create a custom manual colour scale as follows:

#Some test data
dat <- data.frame(x=runif(10),y=runif(10),
        grp = rep(LETTERS[1:5],each = 2),stringsAsFactors = TRUE)

#Create a custom color scale
library(RColorBrewer)
myColors <- brewer.pal(5,"Set1")
names(myColors) <- levels(dat$grp)
colScale <- scale_colour_manual(name = "grp",values = myColors)

and then add the color scale onto the plot as needed:

#One plot with all the data
p <- ggplot(dat,aes(x,y,colour = grp)) + geom_point()
p1 <- p + colScale

#A second plot with only four of the levels
p2 <- p %+% droplevels(subset(dat[4:10,])) + colScale

The first plot looks like this:

and the second plot looks like this:

This way you don't need to remember or check each data frame to see that they have the appropriate levels.

Utilities.sleep(milliseconds) creates a 'pause' in program execution, meaning it does nothing during the number of milliseconds you ask. It surely slows down your whole process and you shouldn't use it between function calls. There are a few exceptions though, at least that one that I know : in SpreadsheetApp when you want to remove a number of sheets you can add a few hundreds of millisecs between each deletion to allow for normal script execution (but this is a workaround for a known issue with this specific method). I did have to use it also when creating many sheets in a spreadsheet to avoid the Browser needing to be 'refreshed' after execution.

Here is an example :

function delsheets(){
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var numbofsheet=ss.getNumSheets();// check how many sheets in the spreadsheet
  for (pa=numbofsheet-1;pa>0;--pa){ 
    ss.setActiveSheet(ss.getSheets()[pa]);
    var newSheet = ss.deleteActiveSheet(); // delete sheets begining with the last one
    Utilities.sleep(200);// pause in the loop for 200 milliseconds
  }
  ss.setActiveSheet(ss.getSheets()[0]);// return to first sheet as active sheet (useful in 'list' function)
}

You need to go to the new folder properties > security tab, and give permissions to the SQL user that has rights on the DATA folder from the SQL server installation folder.

Another way:

Regex.Replace(urlString, "www.(.+)", "$1");

Since I don't need to loop entire collection, I think it is better to have helper function like this

/**
 * Check if there is a item in a collection by given key and value
 * @param Illuminate\Support\Collection $collection collection in which search is to be made
 * @param string $key name of key to be checked
 * @param string $value value of key to be checkied
 * @return boolean|object false if not found, object if it is found
 */
function findInCollection(Illuminate\Support\Collection $collection, $key, $value) {
    foreach ($collection as $item) {
        if (isset($item->$key) && $item->$key == $value) {
            return $item;
        }
    }
    return FALSE;
}

In case you need short unique IDs as your filename, try shortuuid, shortuuid uses lowercase and uppercase letters and digits, and removing similar-looking characters such as l, 1, I, O and 0.

>>> import shortuuid
>>> shortuuid.uuid()
'Tw8VgM47kSS5iX2m8NExNa'
>>> len(ui)
22

compared to

>>> import uuid
>>> unique_filename = str(uuid.uuid4())
>>> len(unique_filename)
36
>>> unique_filename
'2d303ad1-79a1-4c1a-81f3-beea761b5fdf'

To display dataframes contained in a list:

display(*dfs)

Say you have commit id 2 after commit 1 you would be able to run:

git diff 2 1 > mypatch.diff

where 2 and 1 are SHA hashes.

You need to run the script as source or the shorthand .

source ./myscript.sh

or

. ./myscript.sh

This will run within the existing shell, ensuring any variables created or modified by the script will be available after the script completes.

Running the script just using the filename will execute the script in a separate subshell.

K8s completely works on the fundamental of the namespace. if you like to release all the resource related to specified namespace.

you can use the below mentioned :

kubectl delete namespace k8sdemo-app

(A==B).all()

test if all values of array (A==B) are True.

Note: maybe you also want to test A and B shape, such as A.shape == B.shape

Special cases and alternatives (from dbaupp's answer and yoavram's comment)

It should be noted that:

• this solution can have a strange behavior in a particular case: if either A or B is empty and the other one contains a single element, then it return True. For some reason, the comparison A==B returns an empty array, for which the all operator returns True.
• Another risk is if A and B don't have the same shape and aren't broadcastable, then this approach will raise an error.

In conclusion, if you have a doubt about A and B shape or simply want to be safe: use one of the specialized functions:

np.array_equal(A,B)  # test if same shape, same elements values
np.array_equiv(A,B)  # test if broadcastable shape, same elements values
np.allclose(A,B,...) # test if same shape, elements have close enough values

pip is designed to upgrade python packages and not to upgrade python itself. pip shouldn't try to upgrade python when you ask it to do so.

Don't type pip install python but use an installer instead.

I prefer the following, as it takes into account an inset. If there is no inset, it will still scroll to the top as the inset will be 0.

tableView.setContentOffset(CGPoint(x: 0, y: -tableView.contentInset.top), animated: true)

On this page, the Arduino sketch defines a couple of Structs (plus a couple of methods) which are then called in the setup loop and main loop. Simple enough to interpret, even for a barely-literate programmer like me.

You can use lightweight solution like ZeroMQ [ zmq/0mq ]. It is very easy to use and dramatically faster then sockets.

The full command is:

dir /b /a-d

Let me break it up;

Basically the /b is what you look for.

/a-d will exclude the directory names.

For more information see dir /? for other arguments that you can use with the dir command.

I use it for an object encapsulating command-line parameters when dealing with pluggable modules. The main program doesn't know what the command-line parameters are for modules that get loaded (and doesn't always even know what modules are being loaded). e.g., main loads A, which doesn't need any parameters itself (so why it should take an extra pointer / reference / whatever, I'm not sure - looks like pollution), then loads modules X, Y, and Z. Two of these, say X and Z, need (or accept) parameters, so they call back to the command-line singleton to tell it what parameters to accept, and the at runtime they call back to find out if the user actually has specified any of them.

In many ways, a singleton for handling CGI parameters would work similarly if you're only using one process per query (other mod_* methods don't do this, so it'd be bad there - thus the argument that says you shouldn't use singletons in the mod_cgi world in case you port to the mod_perl or whatever world).

This will probably only affect a small percentage of people, but in my case my project was using CocoaPods and one of those pods had a sub spec with its own CocoaPods. The solution was to use full angle imports to reference any files in the sub-pods.

#import <HexColors/HexColor.h>

Rather than

#import "HexColor.h"

Try this jQuery:

$(function() {
 // Handler for .ready() called.
});

a = ['1', '1', '1', '1', '1', '1', '2', '2', '2', '2', '7', '7', '7', '10', '10']
print a.count("1")

It's probably optimized heavily at the C level.

Edit: I randomly generated a large list.

In [8]: len(a)
Out[8]: 6339347

In [9]: %timeit a.count("1")
10 loops, best of 3: 86.4 ms per loop

Edit edit: This could be done with collections.Counter

a = Counter(your_list)
print a['1']

Using the same list in my last timing example

In [17]: %timeit Counter(a)['1']
1 loops, best of 3: 1.52 s per loop

My timing is simplistic and conditional on many different factors, but it gives you a good clue as to performance.

I know it's already answered but here is a solution I find more elegant:

arsort($array);
reset($array);
echo key($array);

and voila!

In python, A dynamic array is an 'array' from the array module. E.g.

from array import array
x = array('d')          #'d' denotes an array of type double
x.append(1.1)
x.append(2.2)
x.pop()                 # returns 2.2

This datatype is essentially a cross between the built-in 'list' type and the numpy 'ndarray' type. Like an ndarray, elements in arrays are C types, specified at initialization. They are not pointers to python objects; this may help avoid some misuse and semantic errors, and modestly improves performance.

However, this datatype has essentially the same methods as a python list, barring a few string & file conversion methods. It lacks all the extra numerical functionality of an ndarray.

See https://docs.python.org/2/library/array.html for details.

You need to do something like this:

// instantiate XmlDocument and load XML from file
XmlDocument doc = new XmlDocument();
doc.Load(@"D:\test.xml");

// get a list of nodes - in this case, I'm selecting all <AID> nodes under
// the <GroupAIDs> node - change to suit your needs
XmlNodeList aNodes = doc.SelectNodes("/Equipment/DataCollections/GroupAIDs/AID");

// loop through all AID nodes
foreach (XmlNode aNode in aNodes)
{
   // grab the "id" attribute
   XmlAttribute idAttribute = aNode.Attributes["id"];

   // check if that attribute even exists...
   if (idAttribute != null)
   {
      // if yes - read its current value
      string currentValue = idAttribute.Value;

      // here, you can now decide what to do - for demo purposes,
      // I just set the ID value to a fixed value if it was empty before
      if (string.IsNullOrEmpty(currentValue))
      {
         idAttribute.Value = "515";
      }
   }
}

// save the XmlDocument back to disk
doc.Save(@"D:\test2.xml");

Easy.

var scrollIt = function(time) {
    // time = scroll time in ms
    var start = new Date().getTime(),
        scroll = document.documentElement.scrollTop + document.body.scrollTop,
        timer = setInterval(function() {
            var now = Math.min(time,(new Date().getTime())-start)/time;
            document.documentElement.scrollTop
                = document.body.scrollTop = (1-time)/start*scroll;
            if( now == 1) clearTimeout(timer);
        },25);
